Hi @hara1101kazu

This error can occur if you have any PVC in cluster-1 created without StorageClass requirement in the PVC definition. You can run 'kubectl get pvc -A' command to confirm that. https://github.com/dell/csm-replication/blob/35a4cb11f35050cc1a13550f91dff7c7f632a9b9/repctl/pkg/types/pvc.go#L68C2-L68C2

Once you confirm, we can convert this ticket to see if we can handle this case in repctl. You can also delete that PVC if that's not needed so that repctl can list PVCs. Thanks!

thank you! I was able to solve it successfully. There was a PVC without StorageClass.

Reopening it to capture it as an improvement to be made.
